VENT.

PECIFICATEON forming part of Letters `Patent No. 319,007, dated June 2, 1885.

Application tiled April 3, 1885.

To all whom, it may concern,.-

Beit known that I, l-Inniulnn Mnrzcnn, a citizen of the United States, residing at North Springiield, in the county of Greene and State of Missouri, have invented certain new and useful Improvements in Vents; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same.

My invention relates to improvements in vents,the object of which is to provide a cheap, simple, and durable device for letting air into a beer or other vessel as the liquid is drawn out, or to create a pressure in the vessel, in order to make the liquid iiow more. freely,and at the saine time to prevent the gas in the vessel from escaping, and also to prevent splitting the bung of the keg or vessel. These objects I attain by means of the device illustrated in the accompanying drawings,which form a part of this specification, in which- Figure l is a perspective view of the entire device. Fig. 2 is a section of the saine on the Fig. 3 is a modification in section, showing the rubber tube between two metallic funnel-shaped tubes. Fig. 4 is a view showing the rubber tube. Fig. 5 is a view showing the expansion-tube.

A is a tube, preferably made of brass, but which may be of any desired material, having an opening, au', for the purpose of allowing` air to pass from the atmosphere into the tube D B. A has threads at, preferably out on the outside, for screwing it into tube D B. Part a also has threads a3, preferably cut on the outside, for securing the hose of a force-pump, for the purpose of pumping air into the vessel to create a pressure when desired. The end a" of the tube A is made smaller and projects beyond the threads c, so that it maybe struck with ahamnier or other device without injury to the threads. Part a has the projection c5, to which is secured, by any suitable means, a hollow punch, O, for the purpose of punching a hole part way through the bung of the keg or vessel, so that the part D will not split the bung when being driven, and also to make it more easily driven. Said punch is preferably made with threads on the outside to screw into the opening al, which opening has a slot or opening, o8, for letting ont the chips. Parts (No model.)

a and c5 are of suflicient length to serve as a handle, for the purpose of inserting and drawing` tube D out of the bung when desired. The

threads o? of tube A, shoulder b', for receiving` the projecting flanges of the tubes C and E receiving the tubes G and E and allowing the end e to work freely, and shoulder D, for the purpose of preventing the tube from being driven too far into the bung, which shoulder is preferably formed with au elastic washer, 1 ),which is slipped on and iits closely around part D, forming an air-tight joint where the vent enters the vessel. small, and has a. sharp point, d, so that it may be driven easily, and so. as not to split the bung. The part D has holes d', preferably made flaring outwardly, so as not to clog or fill up. These holes allow the air to pass from the tube into the vessel. Vhen the tube D B is made in more than one part,the partD has threads dt cut on its lupper end, so as to screw into the lower end of barrel band is also made square near its upper end, for attaching a wrench for screwing it into barrel b2, which has threads cut in its lower end to receive the threads of tube di. l

C is a tube having the llange c to rest upon the shoulder b', to hold it in place.

erably made a little larger at its lower end, c, than where it enters the flange c, so that the rubber tube E, when drawn over it, cannot slip or fall off.

E is a tube, made of any suitable flexible ma` terial, preferably of rubber, and is preferably made or formed with a flange at its upper end, c?, so as to fit down upon the shoulder b', making an air-tight joint. or molded that it will stay closed at its lower end, e, so that no air or gas can escape through it out of the vessel, but will allow the air to be drawn into the vessel when there isavacunxn formed by drawing off the liquid; or the air and the washer F, barrel bfor the purpose of4 The part D is made Said l 'tube may be made funnel-shaped, but is pref- This tube is so formed IOO maybe forced into the vessel to create a pressure when desired.

WasherF may be made of any suitable flexible material, but preferably of rubber, so that when the end am is screwed down upon it it presses down uponthe ilanges of G and E and out against the Wall of tube B,thus making an air-tight joint.

rIhere may be a tube, G, l1avingaange,g,to rest upon the shoulder b', for holding the rub'- ber tube in plaee; but this tube maybe omitted when desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is'- l.
